Dose-dependent inactivation of HCoV-229E by Echinaforce. Direct exposure to Echinaforce lead to a dose-dependent inactivation of HCoV-229E. Half-maximal inhibitory concentration, IC50, was calculated as 3.2 μg/ml and complete virus inactivation was achieved at a concentration of 50 μg/ml, while no effect was observed on cell viability (right y-axis). The data shown are representative of three independent experiments (mean ± sd)
